Find the p-value for a left-tailed hypothesis test with a test statistic of z= -1.55. decide whether to reject upper h 0h0 if the level of significance is α=0.10.

p-value = round to four decimal places asneeded

0.0606

Step-by-step explanation:

Given that test statistic for a left tailed test is

z=-1.55

Significance level = 0.10

let us find p value from z value

p value for left tailed is

0.060571

Since p value < 0.10 our alpha, we reject null hypothesis.

p value = 0.0606

Conclusion:  Reject null hypothesis.

There is statistical evidence to show that sample mean is less than population mean.

step-by-step explanation:

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
